Abstract The use of a packet's Time to Live (TTL) (IPv4) or Hop Limit (IPv6) to protect a protocol stack from CPU-utilization based attacks has been proposed in many settings (see for example, RFC 2461). This document generalizes these techniques for use by other protocols such as BGP (RFC 1771), Multicast Source Discovery Protocol (MSDP), Bidirectional Forwarding Detection, and Label Distribution Protocol (LDP) (RFC 3036).
